PREMODULATION FILTER

MODEL PMF10P-SMA

 

 

 

DESCRIPTION

THE PMF10P-SMA PRE-MODULATION FILTER IS DESIGNED TO SUPPLY ADDITIONAL CURRENT DRIVE FOR LOW IMPEDANCE LOADS (COAX CABLE) AT HIGH BIT RATES. THE PMF10P-SMA CAN DRIVE A 75 OHM LOAD IN PARALLEL WITH HIGH CAPACITIVE LOADS AT ±2.5V, 5 MEGA BIT NRZ-L. CONTACT FACTORY FOR INCREASED DRIVE CAPABILITY. THE INPUT LEVEL DETECTOR REMOVES UNDESIRABLE NOISE SPIKES FROM THE PCM DATA PRIOR TO FILTERING.
